Description

本発明は、眼鏡レンズの保持部材及びそれを備えた眼鏡に関し、特に縁無しタイプの眼鏡に好適な眼鏡レンズの保持部材に関する。   The present invention relates to a spectacle lens holding member and spectacles including the same, and more particularly to a spectacle lens holding member suitable for edgeless spectacles.

従来より、眼鏡レンズの周囲をリム等の枠体で保持することなく、ブリッジ及びヨロイにより保持する縁無しタイプの眼鏡が実用化されている。例えば、特許文献１では、ブリッジ及びヨロイを形状記憶合金製の部材で構成し、レンズ部分に形成した穴に部材を差し込んで保持するようにした眼鏡が記載されている。また、特許文献２では、眼鏡レンズに形成した不貫通孔に複数の線材を貫入させ、それぞれの線材を不貫通孔の側壁に押圧させて保持するようにした眼鏡が記載されている。また、特許文献３では、眼鏡レンズの外周部近傍に長孔を形成し、ヨロイ及びブリッジに形成された弾性を有する二股脚部を長孔に挿入して保持するようにした眼鏡が記載されている。   Conventionally, edgeless spectacles that are held by a bridge and an armor without holding the periphery of a spectacle lens by a frame such as a rim have been put into practical use. For example, Patent Document 1 describes a spectacle in which a bridge and an alloy are made of a shape memory alloy member, and the member is inserted and held in a hole formed in a lens portion. Patent Document 2 describes glasses in which a plurality of wire rods are inserted into non-through holes formed in a spectacle lens and each wire rod is pressed against a side wall of the non-through hole and held. Patent Document 3 describes spectacles in which a long hole is formed in the vicinity of the outer peripheral portion of the spectacle lens, and an elastic bifurcated leg portion formed in an armor and a bridge is inserted and held in the long hole. Yes.

特開平７−２８１１３２号公報JP-A-7-281132 特開２００４−５４０７６号公報JP 2004-54076 A 特開２００８−１６４６４６号公報JP 2008-164646 A

特許文献１から３では、ブリッジ及びヨロイに保持部を形成して、保持部を眼鏡レンズに形成した穴に挿入しているが、ブリッジ及びヨロイが円形断面の線材の場合、保持部を挿入した状態で眼鏡レンズが揺動しやすく外れるおそれがある。特許文献３に記載されたように、断面矩形状の保持部を形成する場合には、保持部の加工が難しくなる。   In Patent Documents 1 to 3, a holding part is formed on the bridge and the armor, and the holding part is inserted into a hole formed on the spectacle lens. However, when the bridge and the armor are wires having a circular cross section, the holding part is inserted. In this state, the spectacle lens may easily swing and come off. As described in Patent Document 3, when forming a holding section having a rectangular cross section, it becomes difficult to process the holding section.

また、こうした線材を用いた場合、特許文献１及び３に記載されているように、保持部の先端が眼鏡レンズから突出していると、突出部が不用意に引っ掛かるおそれがあり、外観デザイン上も好ましいものではない。また、眼鏡レンズの表面や縁部に部材を係合させて保持させているので、眼鏡レンズの形状に合わせて部材の形状を形成しなければガタツキが生じるおそれがある。特許文献２では、線材が突出しないように構成されているが、眼鏡レンズの端面に不貫通孔を形成しているため、不貫通孔を形成したレンズ部分の強度が弱くなり、破損するおそれがある。   In addition, when such a wire is used, as described in Patent Documents 1 and 3, if the tip of the holding portion protrudes from the spectacle lens, the protruding portion may be caught carelessly, and the appearance design also increases. It is not preferable. In addition, since the member is engaged with and held on the surface or edge of the spectacle lens, there is a risk of rattling unless the shape of the member is formed in accordance with the shape of the spectacle lens. In Patent Document 2, the wire rod is configured not to protrude. However, since the non-through hole is formed on the end surface of the spectacle lens, the strength of the lens portion in which the non-through hole is formed is weakened and may be damaged. is there.

そこで、本発明は、容易に加工することができるとともに確実に眼鏡レンズを保持することが可能な眼鏡レンズの保持部材及びそれを備えた眼鏡を提供することを目的とするものである。   Therefore, an object of the present invention is to provide a spectacle lens holding member that can be easily processed and can reliably hold a spectacle lens, and spectacles including the same.

本発明に係る眼鏡レンズの保持部材は、少なくとも一方の端部から中央部に向かって折り返すように折り返し部が形成された接続部と、前記折り返し部に突設されているとともに眼鏡レンズに設けられた係合穴に前側から挿着される係合部とを備え、前記係合部は、逆Ｕ字状に形成されて一端部分が前記折り返し部に接続されているとともに他端部分が前記折り返し部と間隔を空けて対向配置されており、前記係合部の前記一端部分及び前記他端部分の外側が前記係合穴の内面に圧接して眼鏡レンズを保持する。さらに、形状記憶合金材料又は超弾性合金材料からなる薄板を切断加工して形成されている。さらに、前記係合部は、前記一端部分及び前記他端部分の外側に前記係合穴の内面に係止する係止手段を有している。   The spectacle lens holding member according to the present invention includes a connection portion formed with a folded portion so as to be folded back from at least one end toward the center portion, and is provided on the spectacle lens while projecting from the folded portion. An engagement portion inserted into the engagement hole from the front side, wherein the engagement portion is formed in an inverted U shape, one end portion is connected to the folded portion, and the other end portion is folded. The outer end of the one end portion and the other end portion of the engaging portion is pressed against the inner surface of the engaging hole to hold the spectacle lens. Furthermore, it is formed by cutting a thin plate made of a shape memory alloy material or a superelastic alloy material. Further, the engaging portion has a locking means for locking to the inner surface of the engaging hole outside the one end portion and the other end portion.

本発明に係る眼鏡は、上記の保持部材と、前記保持部材により保持された眼鏡レンズとを備えている。さらに、前記眼鏡レンズは、前記係合穴が設けられた係合部材が固着されている。   The eyeglasses according to the present invention include the holding member and a spectacle lens held by the holding member. Furthermore, the eyeglass lens has an engagement member provided with the engagement hole fixed thereto.

本発明は、上記のような構成を有することで、容易に加工することができるとともに確実に眼鏡レンズを保持することが可能となる。   By having the above-described configuration, the present invention can be easily processed and can reliably hold the spectacle lens.

以下、本発明に係る実施形態について詳しく説明する。なお、以下に説明する実施形態は、本発明を実施するにあたって好ましい具体例であるから、技術的に種々の限定がなされているが、本発明は、以下の説明において特に本発明を限定する旨明記されていない限り、これらの形態に限定されるものではない。   Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

図１は、本発明に係る眼鏡レンズの保持構造を備えた眼鏡に関する平面図（図１（ａ））及び正面図（図１（ｂ））である。眼鏡１は、左右一対の眼鏡レンズ２と、眼鏡レンズ２の間に配置されて眼鏡レンズ２を保持するブリッジ３と、ブリッジ３に取り付けられた左右一対の鼻パッド４と、眼鏡レンズ２のブリッジ３とは反対側に配置されて眼鏡レンズ２を保持する左右一対のヨロイ５と、ヨロイ５にそれぞれ取り付けられるテンプル６と、テンプル６に挿着されたモダン７とを備えている。なお、本明細書では、眼鏡１の正面側を前側とし、背面側を後側とする。   FIG. 1 is a plan view (FIG. 1 (a)) and a front view (FIG. 1 (b)) relating to spectacles equipped with a spectacle lens holding structure according to the present invention. The spectacles 1 include a pair of left and right spectacle lenses 2, a bridge 3 disposed between the spectacle lenses 2 and holding the spectacle lens 2, a pair of left and right nose pads 4 attached to the bridge 3, and a bridge between the spectacle lenses 2. 3, a pair of left and right armor 5 that holds the spectacle lens 2, a temple 6 that is attached to the armor 5, and a modern 7 that is inserted into the temple 6. In the present specification, the front side of the glasses 1 is the front side, and the back side is the rear side.

眼鏡レンズ２を保持する保持部材であるブリッジ３及びヨロイ５は、後述するように、それぞれ眼鏡レンズ２に形成された係合穴に係合部を挿着して取り付けられている。ブリッジ３及びヨロイ５は、形状記憶合金、超弾性合金等の金属材料からなり、眼鏡レンズの保持部材としては、例えば、こうした特性を示すニッケルチタン合金材料が好ましい。この例では、金属製薄板をレーザ加工等により切断加工したものを用いており、ブリッジ３及びヨロイ５を簡単に精度よく成形加工することができる。ブリッジ３及びヨロイ５を薄板により成形加工することで、眼鏡を前側から見た場合、ブリッジ３及びヨロイ５が同じ厚さで左右方向に直線状にデザインされるようになり、眼鏡のデザイン性を高めることができる。   As will be described later, the bridge 3 and the alloy 5 that are holding members for holding the spectacle lens 2 are attached to the engagement holes formed in the spectacle lens 2 by inserting the engaging portions. The bridge 3 and the alloy 5 are made of a metal material such as a shape memory alloy or a superelastic alloy, and as a holding member for the spectacle lens, for example, a nickel titanium alloy material exhibiting such characteristics is preferable. In this example, a metal thin plate cut by laser processing or the like is used, and the bridge 3 and the alloy 5 can be formed easily and accurately. By forming the bridge 3 and the armor 5 with a thin plate, when the glasses are viewed from the front side, the bridge 3 and the armor 5 are designed to be linear in the left-right direction with the same thickness, thereby improving the design of the glasses. Can be increased.

図２は、ブリッジ部分に関する一部拡大平面図（図２（ａ））及びヨロイ部分に関する一部拡大平面図（図２（ｂ））である。ヨロイ部分については、左右のヨロイ５は、左右対称に配置された同一形状に形成されているため、右側のヨロイ５のみ図示し、左側のヨロイ５については省略した。   FIG. 2 is a partially enlarged plan view relating to the bridge portion (FIG. 2A) and a partially enlarged plan view relating to the armored portion (FIG. 2B). About the armor part, since the right and left armor 5 are formed in the same shape arranged symmetrically, only the right armor 5 is illustrated and the left armor 5 is omitted.

ブリッジ３は、前側に膨らむように湾曲形成された接続部３０の両端部３０ａ及び３０ｂにおいて、後側に折り返し部３１ａ及び３１ｂが形成されている。折り返し部３１ａ及び３１ｂの後側には、それぞれ逆Ｕ字状の係合部３２ａ及び３２ｂが突設されている。   The bridge 3 is formed with folded portions 31a and 31b on the rear side at both end portions 30a and 30b of the connecting portion 30 formed so as to bend toward the front side. On the rear side of the folded portions 31a and 31b, inverted U-shaped engaging portions 32a and 32b are projected.

折り返し部３１ａ及び３１ｂは、それぞれ接続部３０の両端部３０ａ及び３０ｂから中央部に向かって折り返すように形成されており、折り返した部分の幅は、接続部３０とほぼ同じ幅に形成されている。そして、両端部３０ａ及び３０ｂの幅は、接続部３０並びに折り返し部３１ａ及び３１ｂよりも幅広に形成されている。折り返し部３１ａ及び３１ｂの後側の側端は、係合部３２ａ及び３２ｂを眼鏡レンズ２の係合穴２０ａ及び２０ｂに挿着した場合に、それぞれ左右の眼鏡レンズ２の前側に当接するように設定されている。   The folded portions 31 a and 31 b are formed so as to be folded back from the both end portions 30 a and 30 b of the connection portion 30 toward the center portion, respectively, and the width of the folded portion is formed to be substantially the same width as the connection portion 30. . The widths of both end portions 30a and 30b are formed wider than the connection portion 30 and the folded portions 31a and 31b. The rear side ends of the folded portions 31a and 31b are in contact with the front sides of the left and right eyeglass lenses 2 when the engaging portions 32a and 32b are inserted into the engagement holes 20a and 20b of the eyeglass lens 2, respectively. Is set.

係合部３２ａ及び３２ｂは、逆Ｕ字状に形成されており、接続部３０の端部側に位置する一端部分３３ａ及び３３ｂがそれぞれ折り返し部３１ａ及び３１ｂの根元部分に接続されて一体形成されている。一端部分３３ａ及び３３ｂは、外側の側端が鋸歯状にギザギザに形成されており、各尖端が折り返し部３１ａ及び３１ｂに向かって傾斜するように形成されている。そのため、係合部３２ａ及び３２ｂを係合穴２０ａ及び２０ｂに挿入する場合には一端部分３３ａ及び３３ｂに形成された鋸歯状の尖端が引っ掛かることなくスムーズに挿入することができるが、係合部３２ａ及び３２ｂを係合穴２０ａ及び２０ｂから引き抜く場合には、鋸歯状の尖端が引っ掛かりやすくなり、引き抜きにくくなるように設定されている。   The engaging portions 32a and 32b are formed in an inverted U shape, and are integrally formed by connecting one end portions 33a and 33b located on the end portion side of the connecting portion 30 to the root portions of the folded portions 31a and 31b, respectively. ing. The one end portions 33a and 33b are formed so that the outer side ends are serrated in a serrated shape, and the respective tip ends are inclined toward the folded portions 31a and 31b. Therefore, when the engaging portions 32a and 32b are inserted into the engaging holes 20a and 20b, the serrated tip formed on the one end portions 33a and 33b can be smoothly inserted without being caught. When 32a and 32b are pulled out from the engagement holes 20a and 20b, the saw-toothed tip is set so as to be easily caught and difficult to pull out.

接続部３０の中央側に位置する係合部３２ａ及び３２ｂの他端部分３４ａ及び３４ｂは、折り返し部３１ａ及び３１ｂの先端部分との間に間隔を空けて対向配置されており、外側の角部が鋭角状に形成されている。そのため、係合部３２ａ及び３２ｂを係合穴２０ａ及び２０ｂに挿入する場合には他端部分３４ａ及び３４ｂに形成された外側の角部が引っ掛かることなくスムーズに挿入することができるが、係合部３２ａ及び３２ｂを係合穴２０ａ及び２０ｂから引き抜く場合には、外側の角部が引っ掛かりやすくなり、引き抜きにくくなるように設定されている。係合部３２ａ及び３２ｂは、一端部分３３ａ及び３３ｂから後側に延設されて折り返すように形成された湾曲部分までが次第に幅が狭くなるようにテーパ状に設定されて湾曲部分で最も幅が狭くなり、湾曲部分から他端部分３４ａ及び３４ｂにかけて次第に幅が広くなるように設定されている。そして、係合部３２ａ及び３２ｂの一端部分３３ａ及び３３ｂ並びに他端部分３４ａ及び３４ｂの内側の間の間隔は、湾曲部分から次第に拡がるように形成されている。   The other end portions 34a and 34b of the engaging portions 32a and 32b located on the center side of the connecting portion 30 are arranged to face each other with a space between the tip portions of the folded portions 31a and 31b, and the outer corner portions. Is formed in an acute angle shape. Therefore, when the engaging portions 32a and 32b are inserted into the engaging holes 20a and 20b, the outer corner portions formed in the other end portions 34a and 34b can be smoothly inserted without being caught. When the portions 32a and 32b are pulled out from the engagement holes 20a and 20b, the outer corner portions are easily caught and set so as to be difficult to pull out. The engaging portions 32a and 32b are tapered so that the width is gradually narrowed from the one end portions 33a and 33b to the curved portion formed so as to be folded back and folded back, and the width of the curved portion is the largest. The width is set to be narrow and gradually widen from the curved portion to the other end portions 34a and 34b. And the space | interval between the inner side of the one end parts 33a and 33b and the other end parts 34a and 34b of the engaging parts 32a and 32b is formed so that it may spread gradually from a curved part.

眼鏡レンズ２の係合穴２０ａ及び２０ｂは、それぞれ眼鏡レンズ２の前側表面に対してほぼ垂直方向に貫通しており、左右方向に細長く矩形状に形成されている。係合穴２０ａ及び２０ｂの上下方向の幅は、ほぼ均一でブリッジ３の厚さよりもわずかに広くなるように設定されている。係合穴２０ａ及び２０ｂの左右方向の幅は、係合部３２ａ及び３２ｂにおける一端部分３３ａ及び３３ｂの外側から他端部分３４ａ及び３４ｂの外側までの最も幅広の部分よりも狭くなるように設定されている。また、左右方向の幅は、眼鏡レンズ２の前側から後側に行くに従い次第に拡大するように形成されている。   Engagement holes 20a and 20b of the spectacle lens 2 penetrate through the front surface of the spectacle lens 2 in a substantially vertical direction, and are formed in a rectangular shape elongated in the left-right direction. The vertical widths of the engagement holes 20 a and 20 b are set to be substantially uniform and slightly wider than the thickness of the bridge 3. The width in the left-right direction of the engagement holes 20a and 20b is set to be narrower than the widest portion from the outside of the one end portions 33a and 33b to the outside of the other end portions 34a and 34b in the engagement portions 32a and 32b. ing. The width in the left-right direction is formed so as to gradually increase from the front side to the rear side of the spectacle lens 2.

眼鏡レンズ２の度数は、後側表面の曲率を変化させることで調整されるようになる。そのため、係合穴２０ａ及び２０ｂを眼鏡レンズ２の前側表面に対してほぼ垂直方向に形成することで、異なる度数の場合でも前側表面に対して所定の方向に係合穴を形成することができる。そして、折り返し部３１ａ及び３１ｂを眼鏡レンズ２の前側に当接させてブリッジ３を取り付けるため、眼鏡レンズ２の度数の影響を受けることなく取り付けることができる。また、係合部３２ａ及び３２ｂは、係合穴２０ａ及び２０ｂの内面に係合し裏側に係合することがないので、度数の変化に伴う眼鏡レンズ２の裏側表面の曲率の変更に伴って形状を変更する必要がなく、眼鏡レンズ２の度数が変更した場合でも同じ形状のブリッジ３を使用することが可能となる。   The power of the spectacle lens 2 is adjusted by changing the curvature of the rear surface. Therefore, by forming the engagement holes 20a and 20b in a direction substantially perpendicular to the front surface of the spectacle lens 2, the engagement holes can be formed in a predetermined direction with respect to the front surface even in the case of different powers. . And since the folding | returning part 31a and 31b is contact | abutted to the front side of the spectacle lens 2, and the bridge | bridging 3 is attached, it can attach without being influenced by the frequency of the spectacle lens 2. FIG. Further, since the engaging portions 32a and 32b engage with the inner surfaces of the engaging holes 20a and 20b and do not engage with the back side, the curvature of the back side surface of the spectacle lens 2 with the change in the power is changed. It is not necessary to change the shape, and the bridge 3 having the same shape can be used even when the power of the spectacle lens 2 is changed.

ブリッジ３を一対の眼鏡レンズ２にそれぞれ取り付けて接続する場合には、係合部３２ａ及び３２ｂをそれぞれ眼鏡レンズ２の係合穴２０ａ及び２０ｂの前側から挿着して取り付ける。係合部３２ａ及び３２ｂをその後側に突出した先端部となる湾曲部分から係合穴２０ａ及び２０ｂに挿入していき、湾曲部分が係合穴２０ａ及び２０ｂを突き抜けて眼鏡レンズ２の前側に折り返し部３１ａ及び３１ｂが当接した状態に設定することで、挿着される。   When the bridge 3 is attached and connected to the pair of spectacle lenses 2, the engaging portions 32 a and 32 b are inserted and attached from the front side of the engaging holes 20 a and 20 b of the spectacle lens 2, respectively. The engaging portions 32a and 32b are inserted into the engaging holes 20a and 20b from the curved portion that is the tip protruding to the rear side, and the curved portion passes through the engaging holes 20a and 20b and is turned back to the front side of the spectacle lens 2. By setting the parts 31a and 31b in contact with each other, they are inserted.

ブリッジ３が形状記憶合金材料から形成されている場合には、係合部３２ａ及び３２ｂを係合穴２０ａ及び２０ｂに挿入しやすくするために、他端部分３４ａ及び３４ｂが一端部分３３ａ及び３３ｂに近接するように湾曲部分をさらに湾曲変形させておき、係合部３２ａ及び３２ｂを挿着した後に、元の形状に戻すことで、係合部３２ａ及び３２ｂの一端部分３３ａ及び３３ｂ並びに他端部分３４ａ及び３４ｂが係合穴２０ａ及び２０ｂの内面に圧接して係合状態となって固定される。   When the bridge 3 is formed of a shape memory alloy material, the other end portions 34a and 34b are connected to the one end portions 33a and 33b in order to facilitate the insertion of the engaging portions 32a and 32b into the engaging holes 20a and 20b. The curved portions are further curved and deformed so as to be close to each other, and after the engaging portions 32a and 32b are inserted and returned to their original shapes, the one end portions 33a and 33b and the other end portions of the engaging portions 32a and 32b 34a and 34b are brought into press contact with the inner surfaces of the engagement holes 20a and 20b and fixed in an engaged state.

また、ブリッジ３が超弾性合金材料から形成されている場合には、係合部３２ａ及び３２ｂの湾曲部分をそれぞれ眼鏡レンズ２の係合穴２０ａ及び２０ｂに挿入していく。その際に、係合穴２０ａ及び２０ｂの左右方向の幅は、係合部３２ａ及び３２ｂにおける一端部分３３ａ及び３３ｂの外側から他端部分３４ａ及び３４ｂの外側までの最も幅広の部分よりも狭くなるように設定されているので、係合部３２ａ及び３２ｂは、他端部分３４ａ及び３４ｂが一端部分３３ａ及び３３ｂに近接するように湾曲部分がさらに湾曲変形しながら挿入されていくようになる。そして、湾曲部分が係合穴２０ａ及び２０ｂを突き抜けて眼鏡レンズ２の前側に折り返し部３１ａ及び３１ｂが当接した状態に設定すると、係合穴２０ａ及び２０ｂの左右方向の幅は、眼鏡レンズ２の前側から後側に行くに従い次第に拡大するように形成されているので、係合部３２ａ及び３２ｂの他端部分３４ａ及び３４ｂと一端部分３３ａ及び３３ｂとの間が挿入開始時に比べて若干拡がるように湾曲変形する。そのため、係合部３２ａ及び３２ｂを挿入方向とは反対側に引き抜く力に対しては、係合部３２ａ及び３２ｂの他端部分３４ａ及び３４ｂ並びに一端部分３３ａ及び３３ｂが係合穴２０ａ及び２０ｂの内面に圧接して係合状態となって固定される。   When the bridge 3 is formed of a superelastic alloy material, the curved portions of the engaging portions 32a and 32b are inserted into the engaging holes 20a and 20b of the spectacle lens 2, respectively. At that time, the widths of the engaging holes 20a and 20b in the left-right direction are narrower than the widest portion from the outside of the one end portions 33a and 33b to the outside of the other end portions 34a and 34b in the engaging portions 32a and 32b. Thus, the engaging portions 32a and 32b are inserted while the curved portions are further curved and deformed so that the other end portions 34a and 34b are close to the one end portions 33a and 33b. Then, when the bent portions penetrate through the engagement holes 20a and 20b and the folded portions 31a and 31b are in contact with the front side of the spectacle lens 2, the width in the left-right direction of the engagement holes 20a and 20b is set to the spectacle lens 2. Is formed so that it gradually expands from the front side to the rear side, so that the space between the other end portions 34a and 34b and the one end portions 33a and 33b of the engaging portions 32a and 32b slightly expands compared to when the insertion is started. To bend and deform. Therefore, the other end portions 34a and 34b and the one end portions 33a and 33b of the engaging portions 32a and 32b are connected to the engaging holes 20a and 20b with respect to the force with which the engaging portions 32a and 32b are pulled out in the direction opposite to the insertion direction. The inner surface is pressed and fixed in an engaged state.

係合部３２ａ及び３２ｂが係合穴２０ａ及び２０ｂの内面に圧接した状態では、一端部分３３ａ及び３３ｂの外側に形成された鋸歯状の尖端並びに他端部分３４ａ及び３４ｂが係合穴２０ａ及び２０ｂの内面に圧接して係合部３２ａ及び３２ｂが引き抜かれることなくしっかりと固定されるようになる。   In a state where the engaging portions 32a and 32b are in pressure contact with the inner surfaces of the engaging holes 20a and 20b, the serrated tip formed on the outer side of the one end portions 33a and 33b and the other end portions 34a and 34b are engaged with the engaging holes 20a and 20b. The engaging portions 32a and 32b are firmly fixed without being pulled out by being brought into pressure contact with the inner surface of the member.

このように、係合部の一端部分及び他端部分の外側が係合穴の内面に係止して眼鏡レンズが保持されるため、係合部と係合穴との間の２点支持により眼鏡レンズが係合部分でガタツクことなく保持される。また、逆Ｕ字状に形成された係合部を、係合部の厚さよりもわずかに広い幅の係合穴に挿着しているので、係合穴の内部で係合部が回動することはなく、眼鏡レンズをしっかりと保持することができる。   As described above, the outer side of the one end portion and the other end portion of the engaging portion is locked to the inner surface of the engaging hole, and the spectacle lens is held. Therefore, by the two-point support between the engaging portion and the engaging hole. The spectacle lens is held at the engaging portion without rattling. In addition, since the engaging portion formed in an inverted U shape is inserted into the engaging hole having a width slightly larger than the thickness of the engaging portion, the engaging portion rotates inside the engaging hole. The spectacle lens can be held firmly.

また、係合部３２ａ及び３２ｂの他端部分３４ａ及び３４ｂと係合穴２０ａ及び２０ｂとの間には、隙間が形成されているので、この隙間に工具を挿し込み、他端部分３４ａ及び３４ｂを一端部分３３ａ及び３３ｂに近接するように変形させることで、係合部３２ａ及び３２ｂの係合状態を解除して眼鏡レンズ２からブリッジ３を取り外すこともできる。   Further, since a gap is formed between the other end portions 34a and 34b of the engaging portions 32a and 32b and the engaging holes 20a and 20b, a tool is inserted into the gap, and the other end portions 34a and 34b are inserted. The bridge 3 can be detached from the eyeglass lens 2 by releasing the engagement state of the engagement portions 32a and 32b by deforming the first and second end portions 33a and 33b closer to each other.

そして、係合部３２ａ及び３２ｂが眼鏡レンズ２の係合穴２０ａ及び２０ｂに固定された状態では、眼鏡レンズ２を突き抜けた係合部３２ａ及び３２ｂの湾曲部分は丸みを帯びた形状に形成されているため、不用意に接触しても引っ掛かることはない。また、接続部３０の両端部３０ａ及び３０ｂについても丸みを帯びた形状に形成されているので、不用意に接触しても引っ掛かることはない。折り返し部３１ａ及び３１ｂの先端部は、接続部３０と眼鏡レンズ２との間に配置されるため、外側から不用意に接触することが防止される。   When the engaging portions 32a and 32b are fixed to the engaging holes 20a and 20b of the spectacle lens 2, the curved portions of the engaging portions 32a and 32b that penetrate the spectacle lens 2 are formed in a rounded shape. Therefore, even if it touches carelessly, it is not caught. Moreover, since both ends 30a and 30b of the connection part 30 are formed in the rounded shape, even if it contacts carelessly, it does not get caught. Since the tip portions of the folded portions 31a and 31b are disposed between the connection portion 30 and the spectacle lens 2, it is possible to prevent inadvertent contact from the outside.

ヨロイ５は、後側に延設されてテンプル６に接続する細幅に形成された接続部５０を備えている。接続部５０は、中央部分が湾曲形成されており、前側の端部５０ａには、後側に折り返し部５１が延設されており、後側に延設された端部５０ｂは、幅広に形成されてテンプル６と接続する取付穴が５０ｃが形成されている。接続部５０の両端部以外の中央部分の幅はほぼ均一に形成されており、ブリッジ３の接続部３０の幅よりもわずかに狭くなるように設定されている。折り返し部５１の後側には、それぞれ逆Ｕ字状の係合部５２が突設されている。   The armor 5 includes a connecting portion 50 that is formed on the rear side and has a narrow width that connects to the temple 6. The connecting portion 50 is formed with a curved central portion, the front end portion 50a is extended with a folded portion 51 on the rear side, and the rear end portion 50b is formed with a wide width. Thus, a mounting hole 50c for connecting to the temple 6 is formed. The width of the central portion other than both end portions of the connection portion 50 is formed to be substantially uniform, and is set to be slightly narrower than the width of the connection portion 30 of the bridge 3. On the rear side of the folded-back portion 51, inverted U-shaped engaging portions 52 are provided so as to project.

折り返し部５１は、接続部５０の端部５０ａから中央部分に向かって折り返すように形成されており、折り返した部分の幅は、接続部５０とほぼ同じ幅に形成されている。そして、端部５０ａの幅は、接続部５０及び折り返し部５１よりも幅広に形成されている。折り返し部５１の後側の側端は、係合部５２を眼鏡レンズ２の係合穴２１に挿着した場合に、眼鏡レンズ２の前側に当接するように設定されている。   The folded portion 51 is formed so as to be folded back from the end portion 50 a of the connection portion 50 toward the center portion, and the width of the folded portion is formed to be substantially the same as that of the connection portion 50. The width of the end portion 50 a is formed wider than the connection portion 50 and the folded portion 51. The rear side end of the folded portion 51 is set so as to contact the front side of the spectacle lens 2 when the engaging portion 52 is inserted into the engaging hole 21 of the spectacle lens 2.

係合部５２は、逆Ｕ字状に形成されており、接続部５０の端部側に位置する一端部分５３が折り返し部５１の根元部分に接続されて一体形成されている。一端部分５３は、外側の側端が鋸歯状にギザギザに形成されており、各尖端が折り返し部５１に向かって傾斜するように形成されている。そのため、係合部５２を係合穴２１に挿入する場合には一端部分５３に形成された鋸歯状の尖端が引っ掛かることなくスムーズに挿入することができるが、係合部５２を係合穴２１から引き抜く場合には、鋸歯状の尖端が引っ掛かりやすくなり、引き抜きにくくなるように設定されている。   The engaging portion 52 is formed in an inverted U shape, and one end portion 53 located on the end portion side of the connecting portion 50 is connected to the root portion of the folded portion 51 and integrally formed. The one end portion 53 is formed so that the outer side end is serrated in a serrated shape, and each pointed end is inclined toward the folded portion 51. For this reason, when the engaging portion 52 is inserted into the engaging hole 21, the serrated tip formed on the one end portion 53 can be smoothly inserted without being caught, but the engaging portion 52 is inserted into the engaging hole 21. In the case of pulling out, the serrated tip becomes easy to be caught and is set to be difficult to pull out.

接続部５０の中央側に位置する係合部５２の他端部分５４は、折り返し部５１の先端部分との間に間隔を空けて対向配置されており、外側の角部が鋭角状に形成されている。そのため、係合部５２を係合穴２１に挿入する場合には他端部分５４に形成された外側の角部が引っ掛かることなくスムーズに挿入することができるが、係合部５２を係合穴２１から引き抜く場合には、外側の角部が引っ掛かりやすくなり、引き抜きにくくなるように設定されている。係合部５２は、一端部分５３から後側に延設されて折り返すように形成された湾曲部分までが次第に幅が狭くなるようにテーパ状に設定されて湾曲部分で最も幅が狭くなり、湾曲部分から他端部分５４にかけて次第に幅が広くなるように設定されている。そして、係合部５２の一端部分５３及び他端部分５４の内側の間の間隔は、湾曲部分から次第に拡がるように形成されている。   The other end portion 54 of the engaging portion 52 located on the center side of the connecting portion 50 is disposed to face the distal end portion of the folded portion 51 with a space therebetween, and the outer corner portion is formed in an acute angle shape. ing. Therefore, when the engaging portion 52 is inserted into the engaging hole 21, the outer corner portion formed at the other end portion 54 can be smoothly inserted without being caught. In the case of pulling out from 21, the outer corners are easily caught and set so as to be difficult to pull out. The engaging portion 52 is tapered so that the width gradually extends from the one end portion 53 to the curved portion formed so as to be folded back, and the width becomes narrowest at the curved portion. The width is set so as to gradually increase from the portion to the other end portion 54. And the space | interval between the inner side of the one end part 53 and the other end part 54 of the engaging part 52 is formed so that it may spread gradually from a curved part.

眼鏡レンズ２の係合穴２１は、係合穴２０ａ及び２０ｂと同様に、それぞれ眼鏡レンズ２の前側表面に対してほぼ垂直方向に貫通しており、左右方向に細長く矩形状に形成されている。係合穴２１の上下方向の幅は、ほぼ均一でヨロイ５の厚さよりもわずかに広くなるように設定されている。係合穴２１の左右方向の幅は、係合部５２における一端部分５３の外側から他端部分５４の外側までの最も幅広の部分よりも狭くなるように設定されている。また、左右方向の幅は、眼鏡レンズ２の前側から後側に行くに従い次第に拡大するように形成されている。   Similar to the engagement holes 20a and 20b, the engagement hole 21 of the spectacle lens 2 penetrates the front surface of the spectacle lens 2 in a substantially vertical direction, and is formed in a rectangular shape elongated in the left-right direction. . The vertical width of the engagement hole 21 is set to be substantially uniform and slightly wider than the thickness of the armor 5. The width of the engaging hole 21 in the left-right direction is set to be narrower than the widest portion from the outside of the one end portion 53 to the outside of the other end portion 54 in the engaging portion 52. The width in the left-right direction is formed so as to gradually increase from the front side to the rear side of the spectacle lens 2.

ヨロイ５を眼鏡レンズ２にそれぞれ取り付けて接続する場合には、ブリッジ３と同様に、係合部５２を眼鏡レンズ２の係合穴２１の前側から挿着して取り付ける。係合部５２をその後側に突出した先端部となる湾曲部分から係合穴２１に挿入していき、湾曲部分が係合穴２１を突き抜けて眼鏡レンズ２の前側に折り返し部５１が当接した状態に設定することで、挿着される。   When the armor 5 is attached and connected to the spectacle lens 2, the engaging portion 52 is inserted and attached from the front side of the engaging hole 21 of the spectacle lens 2 in the same manner as the bridge 3. The engaging portion 52 is inserted into the engaging hole 21 from the curved portion that is the tip protruding to the rear side, the curved portion penetrates the engaging hole 21, and the folded portion 51 contacts the front side of the spectacle lens 2. It is inserted by setting the state.

ヨロイ５が形状記憶合金材料から形成されている場合には、係合部５２を係合穴２１に挿入しやすくするために、他端部分５４が一端部分５３に近接するように湾曲部分をさらに湾曲変形させておき、係合部５２を挿着した後に、元の形状に戻すことで、係合部５２の一端部分５３及び他端部分５４が係合穴２１の内面に圧接して係合状態となって固定される。   When the armor 5 is made of a shape memory alloy material, in order to make it easier to insert the engaging portion 52 into the engaging hole 21, the curved portion is further arranged so that the other end portion 54 is close to the one end portion 53. After being bent and deformed, the engaging portion 52 is inserted and then returned to its original shape, whereby the one end portion 53 and the other end portion 54 of the engaging portion 52 are brought into pressure contact with the inner surface of the engaging hole 21 and engaged. Fixed as a state.

また、ヨロイ５が超弾性合金材料から形成されている場合には、係合部５２の湾曲部分をそれぞれ眼鏡レンズ２の係合穴２１に挿入していく。その際に、係合穴２１の左右方向の幅は、係合部５２における一端部分５３の外側から他端部分５４の外側までの最も幅広の部分よりも狭くなるように設定されているので、係合部５２は、他端部分５４が一端部分５３に近接するように湾曲部分がさらに湾曲変形しながら挿入されていくようになる。そして、湾曲部分が係合穴２１を突き抜けて眼鏡レンズ２の前側に折り返し部５１が当接した状態に設定すると、係合穴２１の左右方向の幅は、眼鏡レンズ２の前側から後側に行くに従い次第に拡大するように形成されているので、係合部５２の他端部分５４と一端部分５３との間が挿入開始時に比べて若干拡がるように湾曲変形する。そのため、係合部５２を挿入方向とは反対側に引き抜く力に対しては、係合部５２の他端部分５４及び一端部分５３が係合穴２１の内面に圧接して係合状態となって固定される。   When the armor 5 is made of a superelastic alloy material, the curved portions of the engaging portions 52 are respectively inserted into the engaging holes 21 of the spectacle lens 2. At that time, the width in the left-right direction of the engagement hole 21 is set to be narrower than the widest portion from the outside of the one end portion 53 to the outside of the other end portion 54 in the engagement portion 52. The engaging portion 52 is inserted while the curved portion is further curved and deformed so that the other end portion 54 is close to the one end portion 53. When the bent portion penetrates the engagement hole 21 and the folded portion 51 is in contact with the front side of the spectacle lens 2, the width in the left-right direction of the engagement hole 21 is changed from the front side to the rear side of the spectacle lens 2. Since it is formed so as to gradually expand as it goes, it is curved and deformed so that the space between the other end portion 54 and the one end portion 53 of the engaging portion 52 slightly expands compared to the time when the insertion is started. Therefore, the other end portion 54 and the one end portion 53 of the engagement portion 52 are brought into pressure contact with the inner surface of the engagement hole 21 to be engaged with the force that pulls the engagement portion 52 away from the insertion direction. Fixed.

係合部５２が係合穴２１の内面に圧接した状態では、一端部分５３の外側に形成された鋸歯状の尖端及び他端部分５４が係合穴２１の内面に圧接して係合部５２が引き抜かれることなくしっかりと固定されるようになる。   In a state where the engaging portion 52 is in pressure contact with the inner surface of the engaging hole 21, the serrated tip and the other end portion 54 formed on the outer side of the one end portion 53 are in pressure contact with the inner surface of the engaging hole 21. Will be firmly fixed without being pulled out.

係合部５２を眼鏡レンズ２に固定した後、接続部５０の端部５０ｂにテンプル６の端部を取り付けて、ネジ等により取付穴５０ｃに回動可能にテンプル６を接続する。   After the engaging portion 52 is fixed to the spectacle lens 2, the end portion of the temple 6 is attached to the end portion 50b of the connection portion 50, and the temple 6 is connected to the attachment hole 50c by a screw or the like so as to be rotatable.

係合部５２が眼鏡レンズ２の係合穴２１に固定された状態では、眼鏡レンズ２を突き抜けた係合部５２の湾曲部分は丸みを帯びた形状に形成されているため、不用意に接触しても引っ掛かることはない。また、接続部５０の両端部５０ａ及び５０ｂについても丸みを帯びた形状に形成されているので、不用意に接触しても引っ掛かることはない。折り返し部５１の先端部は、接続部５０と眼鏡レンズ２との間に配置されるため、外側から不用意に接触することが防止される。   In a state where the engaging portion 52 is fixed in the engaging hole 21 of the spectacle lens 2, the curved portion of the engaging portion 52 that penetrates the spectacle lens 2 is formed in a rounded shape, so that it is inadvertently contacted. It won't get caught. Moreover, since both ends 50a and 50b of the connection part 50 are formed in the rounded shape, even if it contacts carelessly, it does not get caught. Since the front end portion of the folded portion 51 is disposed between the connection portion 50 and the spectacle lens 2, it is possible to prevent inadvertent contact from the outside.

この例では、ブリッジ３及びヨロイ５は、金属製薄板を切断加工して形成されているため、全体が均一な厚さに形成されている。そのため、幅の広い部分は狭い部分に比べて曲げや捩りに対する強度が高くなるように設定される。ブリッジ３の接続部３０は、ヨロイ５の接続部５０よりも幅が広くなるように設定されているため、左右のテンプル６が開く方向に拡げられた場合には、ヨロイ５の接続部５０の方が開く方向に変形しやすくなり、ブリッジ３の接続部３０は変形しにくくなる。また、接続部３０及び５０の両端部は、幅広に形成されているため、接続部３０及び５０の各端部に形成された折り返し部に変形した影響が及ぶことはほとんどなく、係合部と眼鏡レンズとの間の係合状態はずれ等が生じることなく固定した状態を維持することができる。着用者の頭部のサイズが異なっている場合に、左右のテンプル６の開き具合が異なってくるが、ヨロイ５の変形で主にサイズに対応した調整がなされてブリッジ３の変形が相対的に小さくなる。そのため、左右の鼻パッド４の間隔が変化することがなく、眼鏡１を安定した状態で着用することができる。   In this example, since the bridge 3 and the alloy 5 are formed by cutting a metal thin plate, the whole is formed to have a uniform thickness. For this reason, the wide portion is set to have higher strength against bending and twisting than the narrow portion. Since the connection part 30 of the bridge 3 is set to be wider than the connection part 50 of the armor 5, when the left and right temples 6 are expanded in the opening direction, the connection part 50 of the armor 5 Therefore, the connecting portion 30 of the bridge 3 is hardly deformed. Further, since both end portions of the connection portions 30 and 50 are formed wide, there is almost no influence of deformation on the folded portions formed at the end portions of the connection portions 30 and 50, and the engagement portions and The state of engagement with the spectacle lens can be maintained without being displaced. When the size of the wearer's head is different, the degree of opening of the left and right temples 6 is different, but the deformation of the bridge 3 is relatively adjusted by the deformation of the armor 5 mainly corresponding to the size. Get smaller. Therefore, the distance between the left and right nose pads 4 does not change, and the glasses 1 can be worn in a stable state.

また、左右のテンプル６を上下に互いに反対方向に移動させて捻るようにした場合には、ブリッジ３の接続部３０及びヨロイ５の接続部５０が捩られるように変形するが、眼鏡レンズ２の左右方向に細幅に形成された係合穴２０ａ、２０ｂ及び２１に係合部３２ａ、３２ｂ及び５２が挿着されているため、各係合部が各係合穴で回動したり、ずれたりすることはほとんどなく、眼鏡レンズ２がブリッジ３及びヨロイ５にしっかりと保持されるようになる。   When the left and right temples 6 are moved up and down in opposite directions and twisted, the connecting portion 30 of the bridge 3 and the connecting portion 50 of the armor 5 are deformed to be twisted. Since the engaging portions 32a, 32b, and 52 are inserted into the engaging holes 20a, 20b, and 21 that are formed narrow in the left-right direction, each engaging portion rotates or shifts in each engaging hole. The spectacle lens 2 is firmly held by the bridge 3 and the armor 5.

以上説明した例では、眼鏡レンズの係合穴に係合部を挿着する際に、係合穴の内面に係止する係止手段として、係合部の一端部分に鋸歯状に形成するとともに係合部の他端部分の角部を鋭角に形成するようにしているが、係合部を係合穴から引き抜く場合に係合穴の内面に係止可能であればこうした係止手段以外の手段を用いてもよく、特に限定されない。例えば、係合穴の内面に段差部を形成しておき、他端部分の角部が係止するように設定することもできる。   In the example described above, when the engaging portion is inserted into the engaging hole of the spectacle lens, it is formed in a serrated shape at one end portion of the engaging portion as a locking means for locking to the inner surface of the engaging hole. The corner of the other end portion of the engaging portion is formed with an acute angle. However, when the engaging portion can be pulled out from the engaging hole, it can be locked to the inner surface of the engaging hole. Means may be used and are not particularly limited. For example, a step portion may be formed on the inner surface of the engagement hole, and the corner portion of the other end portion may be set to be locked.

また、鋸歯状の形状をフック状の形状にすることも可能である。また、係合部の一端部分及び他端部分の外側が係合穴の内面に圧接するだけで係合部の引き抜きが防止できる場合には、他端部分を鋸歯状に形成しなくてもよい。   It is also possible to make the sawtooth shape into a hook shape. Further, when the engagement portion can be prevented from being pulled out only by pressing the outer ends of the engagement portion on the inner surface of the engagement hole, the other end portion may not be formed in a sawtooth shape. .

The width of the opening 102 in the minor axis direction is set to be substantially uniform and slightly wider than the thickness of the bridge and armor. The length of the opening 103 in the major axis direction is longer than that of the opening 102, and the width of the opening 103 in the minor axis direction is set to the same width as the opening 102. In the inner surface of the engagement hole provided in the main body 100, a step 104 is formed on one side surface in the long axis direction corresponding to the difference in length between the openings 102 and 103 in the long axis direction. Yes.

係合部材の係合穴に係合部を挿入する場合には、係合部の他端部分が係合穴の開口１０２を通過可能となるように係合部を変形させた後、段差部１０４が形成されていない長軸方向の他方の側面に沿って係合部の一端部分の外側を当接しながら開口１０２に挿入すれば、スムーズに係合部を係合穴に挿入することができる。そして、係合部を挿入した後、他端部分が元の形状に戻ることで、係合穴の内面に係合部の一端部分及び他端部分の外側が圧接して固定される。また、他端部分の外側の角部が段差部１０４に係止することで、係合部が引き抜かれるのを確実に防止することができる。   When the engaging portion is inserted into the engaging hole of the engaging member, after the engaging portion is deformed so that the other end portion of the engaging portion can pass through the opening 102 of the engaging hole, the step portion If the outer end of one end portion of the engaging portion is inserted into the opening 102 along the other side surface in the long axis direction where 104 is not formed, the engaging portion can be smoothly inserted into the engaging hole. . Then, after the engaging portion is inserted, the other end portion returns to its original shape, and the one end portion of the engaging portion and the outside of the other end portion are pressed and fixed to the inner surface of the engaging hole. Further, since the outer corner portion of the other end portion is locked to the stepped portion 104, it is possible to reliably prevent the engaging portion from being pulled out.

以上のように眼鏡レンズに形成された取付穴に係合部材を固着して係合部を固定するようにしているので、係合部材に眼鏡レンズよりも高強度の材料を用いることで、ブリッジ及びヨロイと眼鏡レンズとの接続部分の強度を強化することができる。また、係合部材の内面に形成された段差部に係合部を係止することで、係合部を眼鏡レンズに対して回動やずれを生じることなくしっかりと固定することができ、係合部材から係合部が抜けて外れてしまうのを確実に防止することができる。   As described above, since the engaging member is fixed to the mounting hole formed in the spectacle lens to fix the engaging portion, the bridge is formed by using a material having higher strength than the spectacle lens for the engaging member. And the intensity | strength of the connection part of an armor and a spectacle lens can be strengthened. In addition, by locking the engaging portion to the step portion formed on the inner surface of the engaging member, the engaging portion can be firmly fixed without causing rotation or displacement with respect to the spectacle lens. It is possible to reliably prevent the engaging portion from coming off from the joint member and coming off.

また、接続部３０’の両端部３０ａ’及び３０ｂ’の幅を狭くして略円形状に湾曲形成しているので、左右のテンプル６を開くように拡げると、主に両端部３０ａ’及び３０ｂ’が湾曲変形して接続部３０’から折り返し部３１’が離間するように変形する。そのため、ヨロイ５’の接続部５０’の変形が抑えられて係合部及び係合部材の接続部分へ応力が集中することがなくなり、ブリッジ及びヨロイにより眼鏡レンズを安定して保持することができる。また、左右のテンプル６を上下に移動させて捻るように変形させた場合でも主に両端部３０ａ’及び３０ｂ’が捻るように変形して他の部位の変形が抑えられて眼鏡レンズを安定して保持することが可能となる。   In addition, since both ends 30a 'and 30b' of the connection portion 30 'are narrowed and formed in a substantially circular shape, when the left and right temples 6 are expanded to open, both ends 30a' and 30b are mainly used. 'Is bent and deformed so that the folded portion 31 ′ is separated from the connecting portion 30 ′. Therefore, the deformation of the connecting portion 50 ′ of the armor 5 ′ is suppressed and stress is not concentrated on the connecting portion of the engaging portion and the engaging member, and the spectacle lens can be stably held by the bridge and the armor. . Further, even when the left and right temples 6 are moved up and down and deformed so as to be twisted, deformation is mainly performed so that both end portions 30a ′ and 30b ′ are twisted, and deformation of other parts is suppressed, thereby stabilizing the spectacle lens. Can be held.

以上説明した例では、接続部の端部側に位置する係合部の一端部分を折り返し部の根元部分に一体形成して、接続部の中央側に位置する係合部の他端部分を折り返し部の先端部分と間隔を空けて離間させているが、係合部の他端部分を折り返し部の先端部分に接続して一体形成し、係合部の一端部分を折り返し部の根元部分と間隔を空けて離間させるようにすることもでき、上述した例と同様の作用効果を奏することが可能となる。   In the example described above, one end portion of the engaging portion located on the end portion side of the connecting portion is integrally formed with the root portion of the folding portion, and the other end portion of the engaging portion located on the center side of the connecting portion is folded back. The other end portion of the engaging portion is connected to the distal end portion of the folded portion and integrally formed, and the one end portion of the engaging portion is spaced from the root portion of the folded portion. It is also possible to make them spaced apart, and the same effects as the above-described example can be achieved.
